With clients like Halle Berry and Jessica Chastain, Fiona Stiles is one of the top celebrity makeup artists out there. These are the 9 products she can't live without -- and you shouldn't either

A long-lasting mascara Stiles' new mascara obsession is CoverGirl LashBlast 24 Hour Mascara, $7.99. While it doesn't claim to be waterproof, the formula really stays put -- which is as important on the red carpet as it is in everyday life. "Plus, it gives beautiful, thick lashes with just one coat," says Stiles. "But two coats is always better!"

Seriously. $60 lip balm?! I use Blistex Silk 'n Shine for $4 and it works beautifully. I do see the Ecotools brush set in my local drugstore all the time and always wondered about them. I'll give them a try, since the price is more realistic for me. I'm also curious about the Anastasia brow gel. :)
